SASH-FASTENER.

SIEECIFIGATION forming part of Letters Patent No. 585,110, dated June22, 1897. Application filed February 11, 1897. $erial No. 622,916. (Nomodel.)

T on whom it may concern.-

Be it known that I, ROBERT LEE, a citizen of the United States, residingat Hartwell, in the county of Hamilton and State of Ohio, have inventedcertain new and useful Improvements in a CombinedAntirattler,Ventilator, and Locking Attachment for Windows, of which thefollowing is a specification.

Myinvention relates to locking attachments for sliding window-sashes,or, more particularly speaking, to a combined antirattler, ventilator,and locking device whereby both window-sashes may be held firmly lockedwhen closed against both surreptitious opening from the outside andrattling and either sash or both sashes held partly open forventilation, but firmly locked in such partly open condition againstfurther opening for intrusion or surreptitious entrance; and myinvention, pursuant thereto, consists in the novel features ofarrangement, construction, and operation, such as are hereinafter fullydescribed, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a broken inside frontelevation of a window, showing the two sliding sashes, with the upperone slightly lowered for ventilation and both of them locked together bymeans of my device against further intrusive opening and also fromrattling; Fig. 2, a full-sized inside front elevation showing abroken-off meeting 7 corner of a pair of sashes with my device appliedthereto, said sashes being therein shown in their completely-closedlocked position with their meeting-rails in line; Fig. 3, a brokensectional elevation of Fig. 2, looking from left to right; and Fig. 4,an elevation of the back of my locking device detached from the window,showing it in its locked position, same as in the preceding views.

A and A represent the two customary stiles or vertical side bars of thelower sash, and B and B those of the upper sash.

a is the upper horizontal cross-bar of the lower sash, and b the lowerhorizontal crossbar of the upper sash, both bars (a and b) constitutingthe usual meeting-rails of the two sliding sashes.

a represents the usual ogee upper extensions of the lower sash stiles,and b the pendent extensions of the upper-sash stiles. EX- tensions aare the upright integral continuations of the two side stiles of thelower sash, commonly constructed on sashes in general use, so as toproject upward beyond the plane of the cross bar or rail Ct. The pendentextensions b' are corresponding formations on the upper sash, only viceversa.

O is the vertical strip in the jamb or window casing between the stilesof the two sashes and having the customary guideways at either side forthe Vertical movements of said sashes.

My locking device is attached partly to the upper extension of thelower-sash stile A and partly to the stile B and lies at its lower endin the space between the said stiles A and B and is composed of thefollowing elements:

a vertical base-plate D, having countersunk screw-holes d; a bar orplate E, hinged (preferably by a rule-joint) to the upper end of saidbase-plate D; a swinging lock-lever F, pivotally connected at its lowerend to the upper end of hinged bar E; a cam G, mounted on the pivot-pinof lever F at the opposite side of bar E, contiguous to the latter;aspring pawl or latch e, pivotally mounted in lateral ears f on thelever F, with its lower end engaging the upper end of bar E when thelocking engagement is effected, as seen in all the views; adownwardly-turned lug or hook f, constructed on the lever F near itsupper end and on the rear side somewhat above the said cam, and akeeper-plate H, which has an open slot or notch h and a pair ofcountersunk screw-holes h. v

Base-plate D is attached to the lower portion of the upright integralextension at of the side stile A by means of horizontally-disver(comprising bars E and F) is swung upward from a horizontal position toa vertical one, the lever F not then being in latched engagement withthe bar E, but swung to the left, so that hook f may enter the open sloth and then engage the inclined beveled inner face f of the lower edge ofthe notch, as best seen in Figs. 2 and 3, when said lever F is swung tothe right into a perpendicular position. The spring latch or pawl epositively prevents the lever F swinging sidewise, either accidentallyor by stealth, from the outside, and the cam G, which projects frombeyond the vertical plane of the hinged plate E in line with thekeeper-plate H, abuts the bottom of the latter (when the said lockleveris in perpendicular position) and positively prevents either sash beingmoved or slid up or down, and also thrusts the two sashes vertically inopposite directions (the upper sash upward and the lower sash downward)against the top and bottom, respectively, of the window-easing, thusforming a very effective antirattler, as both sashes are renderedperfectly tight by their said pressing impingement at top and bottom.

In order to properly set the keeper-plate in place on the stile B, so asto make the antirattling operation effective, I first secure thelock-lever attachment in place on the lower sash; then I swing the leverF to the left in its horizontal position; then Ilay the keeperplate 011the face of stile B, with its anchorpins j (seen in dotted lines in Fig.3) sunk into the wood and its lower end resting on the fiat side J ofthe cam; then I raise or swing the lever F to the right, which bringsthe cam to forcibly bear against the lower end of plate II, causing thelatter torise vertically and its anchor-pinsj to cut upwardly into thewood, which firmly sets it, and then I apply the screws into thekeeper-plate H to secure it in place. Thus anchored and secured anygreat pressure brought by the cam on the keeper-plate will not cause thelatter to give, and the two sashes must therefore have a naturaltendency to be thrust in opposite directions against the top and bottomof the casing, as stated.

The hook f is beveled on its under side to suit the inner bevel of thenotched keeperplate II, and thus the two sashes are drawn tightlytogether and clamped firmly on the jamb-strip O, (the stile A on oneside the jamb-strip and the stile B on the other,) so that no rattlingcan possibly take place when thesashes are partly open for ventilation,especially at the joint between the two sashes. The hook engagement alsoprevents the locklever toppling forward from looking action.

It will be seen in Figs. 1, 2, and 3 that the upper end a of the lever Fis bent or flared so as to coy er the thumb end of the springlatch c.This precaution is taken to form a guard over and protect saidthumb-latch against surreptitious depression or releasing from theoutside or access from above and making it'impossible for the intruderto pick the look at that point, which is very essential.

By placing the device on the sash-stiles and using horizontally-disposedscrews, the intruder cannot readily pick the lock, nor can he pry orpull the screws from position, as

he can when they are entered vertically in a look at the center of themeeting-rails. The

screws must thus break before the window will give.

To open the window, all that is requisite is to depress the thumb-latcha so that the lever F may be rocked to the left and its hook f releasedfrom the keeper-plate II, and then the hinged bar E (with said lever Fthereon) swung forward toward the operator till they rest 011 theextension at.

To make the window doubly secure against intrusion and rattling, a pairof my devices may be attached, one at either end the meeting-rails onboth stiles of the sashes.

It is obvious (without showing it in the drawings) that the device maybe used on plain sashes having no stile extensions a by simply attachingthe base-plate D horizontally 011 the upper endof the stile; but this ofcourse would involve the use of perpendicular screws, which would not beas effective asif placed horizontal, for the reasons hereinbeforestated; The cammay be dispensed with, if desired, and the hookengagement with the keeper-plate be sufiicient for looking, but theeffect would not be so powerful and effective.

1. A window-fastenin g device composed of a base-plate D; rock-bar Ehinged at itslower end to plate D; lock-lever F having a hook fconstructed thereon and swung on said bar E; thumb-latch e on the leverF; and one or more notched keeper-plates II, h; the whole beingconstructed and arranged on the stiles of the windowsashes,substantially as herein set forth.

2. A window-fastening device composed of a base-plate D; rock-bar Ehinged at its lower end to plate D'; a flared or elbowed lock-lever Fhaving hook f thereon and swung on said rock-bar E; cam G mounted on thepivot-pin at the opposite side of bar E, contiguous'to the latter;spring thumb-latch or pawl c on the lever F; and one or more notchedkeeperplates II, h; the whole being attached to the stiles of thesashes, and constructed and adapted to operate whereby the sashes may belocked entirely closed; or locked partly open for ventilation; and alsopreventedfrom rattling, substantially as herein set forth.

In testimony of which invention I have hereunto set my hand.

ROBERT LEE.
